Google descubrió un truco muy estúpido para que la inteligencia artificial te responda MUCHO mejor. Mientras todo el mundo busca el prompt perfecto, escribe instrucciones complejas y técnicas con nombres elegantes... unos investigadores de Google descubrieron que lo que mejor funciona es copiar y pegar tu pregunta dos veces.  ¡Sí, así de simple! Le mandás el mismo texto dos veces seguidas y la IA responde mejor. Probaron con Gemini, ChatGPT, Claude y DeepSeek: en matemáticas, razonamiento y comprensión lectora mejoró en todo. En un caso, un modelo pasó de 21% de precisión a 97%. ¿Y por qué carajo funciona esto? Porque la IA lee tu mensaje una sola vez, de izquierda a derecha, sin poder volver atrás. Si tu pregunta está al final, todo el contexto de antes se procesó sin saber qué le ibas a preguntar. Es como leer un capítulo entero de un libro y recién al final alguien te dice: "ah, buscá cuántas veces aparece la palabra perro". Ya es tarde. Pero si lo leés dos veces, la segunda vez ya sabés qué buscar. Mientras vos buscabas el prompt perfecto, la respuesta era Ctrl+C, Ctrl+V. A veces la solución más bruta es la más inteligente.

La educación en México es deficiente, y lo más deficiente, según mi experiencia como profesor universitario, es la educación matemática. Y el problema no son las matemáticas sino, en general, los profesores de matemáticas.

🚨🏟️ CONFIRMED: Three teams will have the Estadio Azteca/Banorte as their HOME STADIUM after the 2026 FIFA World Cup. CLUB AMERICA, CRUZ AZUL, and ATLANTE. Atlante is reportedly set to return to Liga MX for the Apertura 2026. ✍🏼

Mexico City just announced a new chatbot called XOLI to guide tourists during the FIFA World Cup. 🇲🇽 It probably cost millions of pesos to build and promote. So I asked it a simple question👇 “Where can I find the best tacos in CDMX?” It crashed. 🤦‍♂️

🚨 Do you understand what just happened.. the owner of OnlyFans just died at 43.. Leonid Radvinsky.. the man made $3 billion off a platform where other people sell themselves.. he took 20% of every transaction.. every video.. every message.. every tip.. while creators fought algorithms and chargebacks and deplatforming threats just to make rent.. he sat at the top collecting a cut of their bodies.. and everyone called him a "tech founder".. the man wasn't a tech founder.. he was the most successful middleman in history.. and the wildest part.. OnlyFans was profitable from day one.. no VC money.. no IPO.. because when your business model is taking a fifth of what someone earns from their own skin.. you don't need investors.. you need creators desperate enough to not ask questions.. he had $3 billion and still couldn't beat cancer at 43.. what exactly are we all racing toward.

Mexico is the absolute outlier in the OECD: workers log the most hours on Earth (~2,200+ annually) yet deliver relatively little economic output per hour—despite huge advantages like proximity to the USA. Something went seriously wrong. My take: the education system. Even grads from top STEM unis often have shockingly weak fundamentals (based on interviews). Sure, brilliant Mexicans exist, but the system fails the average citizen badly. Work smarter, not longer. Fix education → unlock potential. Study math, just ask Peru 🇵🇪

Brad Pitt spent years buying up every neighbouring property around his Los Feliz estate. When he acquired the home of an elderly widower named John, already in his 90s, he could have asked him to leave. Instead, he told him he could stay for free for the rest of his life. John ended up living to 105. The story only came out because Pitt’s former neighbour, Cassandra Peterson, mentioned it in passing to People magazine. No announcement, no headlines. Just a good thing done quietly.
